I suppose any gains would depend on how sparse /compressible the data
you are holding in RAM is.

If you're on an eternal quest for more RAM, have you looked at using an
NVMe SSD device, or an UltraDIMM? They may not perform as fast as RAM,
but you can get a lot more space for less money, so the capacity may
make up for the shortfall in performance.
